Re: backward compatibility and more

I respond to myself for some questions:

I made it. The old interface is still available, the new is used if the value 
in %style_map is a hash reference.

I didn't do that, as now with the new interface function references are used.
This issue is obsolete.

This wasn't totally true. In fact texi2html verifies that the accented letter
is a precomposed unicode character. Thus I think this isn't a good feature 
as all the characters can be composed in unicode and thus all the characters
should be available. Moreover it should be rather easy to output decomposed
characters whenever the precomposed one doesn't exist. It could even be better
to use decomposed characters only and use Unicode::Normalize to normalize to
a given form. 

Still on that subject, I think the form C would be the better one when 
outputting utf8.
See

or

for more on that subject.
